The U.S. Navy is showing off some unlikely recruits in California.

Its Marine Mammal Program conducted training exercises Tuesday in the San Francisco Bay using sea lions and dolphins that have been trained to perform underwater surveillance for object detection, location, marking, and recovery.

In a full-scale regional exercise focusing on the state's response and recovery to multiple terrorist attacks at Bay Area ports, federal, state, and city officials took part in the Golden Guardian emergency preparedness program.

At Pier 48 in San Francisco, the city's police and fire departments, along with its Emergency Operations Center, conducted a drill demonstrating the ability of dolphins and California Sea Lions to help protect coastal areas from maritime attacks.

California Sea Lions

California Sea Lions are trained at the Navy Marine Mammal Program in San Diego to patrol coastal waters and search out foreign objects like mines, IEDs (improvised explosive devices), and human threats.

With incredibly sensitive sonar able to detect objects and people that might otherwise be obscured in dark or cloudy waters, the dolphin is used to locate a person, dropping a marker in the water to identify the target's location.

"Exercises like this, which allow cooperation between federal, state, and local agencies, are valuable training opportunities for all involved in ensuring public safety," said Tom LaPuzza, public affairs officer for the Navy's Marine Mammal Program.
